Hereinafter, some example embodiments of a method and system for immediate or prompt trading of a cryptocurrency are described.
FIG. 3 illustrates an example of a process of processing a transfer transaction according to some example embodiments.
A cryptocurrency trading system 310 serves as a cryptocurrency exchange to provide a cryptocurrency trading service and may be implemented by the server 150 of FIGS. 1 and 2.
The term “user” used herein may represent a portion of a plurality of users using the cryptocurrency trading system 310, and may represent at least one of the plurality of electronic devices 110, 120, 130, and 140.
Also, the term “first party exchange” may represent the cryptocurrency currency system 310's own exchange and the term “second party exchange” may represent another exchange that is a target exchange.
FIG. 3 illustrates an example of a transfer from a first party exchange of the cryptocurrency trading system 310 to a second party exchange 30.
1) Trading Scheme Using a Blockchain Network:
In response to receiving a transfer request to the second party exchange 30 from a user using the first party exchange, the cryptocurrency trading system 310 proceeds with a transfer transaction to the second party exchange 30 through a blockchain network 330.
That is, the cryptocurrency trading system 310 creates a transaction in response to the transfer request to the second party exchange 30, applies a fee rate to the corresponding transaction, and then submits the transaction to the blockchain network 330. When the transaction submitted to the blockchain network 330 is discovered and mined by a miner, a cryptocurrency of a transfer request quantity is transferred on the blockchain network 330 and the transfer transaction is completed accordingly.
Here, in the case of the transaction through the blockchain network 330, a processing time of the transfer transaction is determined based on a situation of the blockchain network 330 or a fee rate applied to the corresponding transaction.
A trading scheme that involves creating a transaction for transfer corresponding to each request and using the blockchain network 330 may increase transaction priority by raising a fee amount. If mining is delayed due to a low fee rate or a network situation, a relatively long time may pass before the transfer transaction is completed.
2) Trading Scheme Using a First Party Exchange Account:
To outperform the issue found in the trading scheme using the blockchain network 330, the cryptocurrency trading system 310 may provide a cryptocurrency trading service in a structure that allows an immediate transfer. According to some example embodiments, an immediate transfer may be a transfer that is immediate or prompt.
In response to receiving a transfer request to the second party exchange 30 from the user using the first party exchange, the cryptocurrency trading system 310 may more rapidly process a transfer through an internal transaction using a first party exchange account opened on the second party exchange 30 instead of the transaction using the blockchain network 330.
The term “first party exchange account” used herein refers to a first party account of the cryptocurrency trading system 310 (the terms “first party exchange account” and “first party account” may be interchangeably used throughout) opened on another exchange, for example, the second party exchange 30, and may support an internal transaction on the second party exchange 30 through application programming interface (API) calling. That is, the first party exchange account may be opened on the second party exchange 30 to enable an internal transaction on the second party exchange 30, and may also correspond to the first party account of the cryptocurrency trading system 310 and deposit, withdrawal, and balance inquiry, etc., thereof may be manageable by the cryptocurrency trading system 310 accordingly.
FIG. 4 is a diagram illustrating an example of components includable by a processor of a server according to some example embodiments, and FIG. 5 is a flowchart illustrating an example of a method performed by a server according to some example embodiments.
The server 150 according to some example embodiments may be implemented as the aforementioned cryptocurrency trading system 310. Here, the cryptocurrency trading system 310 serves as a platform that provides a cryptocurrency trading service, and, particularly, may provide the cryptocurrency trading service in a structure that allows an immediate transaction between cryptocurrency exchanges. According to some example embodiments, an immediate transaction may be a transaction that is immediate or prompt.
Referring to FIG. 4, to perform the cryptocurrency trading method of FIG. 5, the processor 222 of the server 150 may include a transaction processing 410 and/or a settlement processing 420. Depending on some example embodiments, the components of the processor 222 (e.g., the transaction processing 410 and/or the settlement processing 420) may be selectively included in or excluded from the processor 222. Also, depending on some example embodiments, the components of the processor 222 may be separated or merged for representations of functions of the processor 222. According to some example embodiments, the transaction processing 410 and/or the settlement processing 420 may be implemented using processing circuitry.
The processor 222, and/or the components of the processor 222, may control the server 150 to perform operations S510 and S520 included in a cryptocurrency trading method of FIG. 5. For example, the processor 222, and/or the components of the processor 222, may be configured to execute an instruction according to a code of at least one program and a code of an OS included in the memory 221.
Here, the components of the processor 222 may be representations of different functions performed by the processor 222 in response to an instruction provided from the program code stored in the server 150. For example, the transaction processing 410 may be used as a functional representation of the processor 222 that controls the server 150 to process a transfer transaction in response to the instruction.
The processor 222 may read an instruction from the memory 221 to which instructions associated with control of the server 150 are loaded. In this case, the read instruction may include an instruction for controlling the processor 222 to perform the following operations S510 and S520. The following operations S510 and S520 may be performed in order different from order illustrated in FIG. 5 and a portion of operations S510 and S520 may be omitted. Alternatively, an additional process may be further included.
Referring to FIG. 5, in operation S510, in the case of receiving a transfer request from a first party exchange provided by the cryptocurrency trading system 310 to a second party exchange, the transaction processing 410 may process an immediate transfer through an internal transaction using a first party exchange account opened on the second party exchange in response to the received transfer request. The transaction processing 410 may process the transfer transaction requested from the user through a trading scheme using the first party exchange account opened on the second party exchange instead of a trading scheme using the blockchain network 330. That is, the transaction processing 410 may process an immediate (or prompt) withdrawal using the first party exchange account that is a common account for a plurality of users using the first party exchange.
The cryptocurrency trading system 310 may provide a user interface for a transfer request and may receive information about the transfer request through the user interface. Here, the user interface may include an option for a trading scheme. The option for the trading scheme may include 1) the trading scheme using the blockchain network 330 and 2) the trading scheme using the first party exchange account. Depending on some example embodiments, when the first party exchange account is opened on another exchange, that is, a second party exchange to which the user desires to transfer an amount (e.g., an amount of cryptocurrency), the transaction processing 410 may include, in the user interface, an option input interface for an option for a trading scheme selectable from the user and may provide the user interface. The transaction processing 410 may process the transfer transaction (e.g., funds transfer) through one of 1) the trading scheme using the blockchain network 330 and/or 2) the trading scheme using the first party exchange account, according to a user selection input through the user interface.
In operation S520, the settlement processing 420 may process a settlement of the first party exchange account using the transaction through the blockchain network 330. The settlement processing 420 may process the transfer transaction in the first party exchange account on the second party exchange through the blockchain network 330 as a settlement according to the immediate transfer. According to some example embodiments, in operation S520 the settlement processing 420 may process the settlement of the first party exchange account as a settlement transaction through the blockchain network 330. The settlement transaction may settle the amount of the transfer transaction performed in operation S510. According to some example embodiments, the second party exchange may be implemented using the server 160.
Some example embodiments may support an immediate transaction through offset processing or an algorithm equivalent thereto, rather than a transaction through the blockchain network 330 between the first party exchange and the second party exchange. For the immediate transaction, the balance of the first party exchange account on the second party exchange may be maintained at a predetermined (or, alternatively, desired) level or more at all times. To this end, an amount to be deposited in the second party exchange may be calculated through a settlement and may be transferred to the first party exchange account on the second party exchange through the transaction scheme using the blockchain network 330.
FIG. 6 is a flowchart illustrating an example of an immediate transfer process according to some example embodiments.
Referring to FIG. 6, in operation S61, the transaction processing 410 may receive a transfer request from a user, for example, using a first party exchange. The transfer request may include a specific wallet address (hereinafter, referred to as a recipient wallet address) to which the user desires to transfer an amount and/or a cryptocurrency quantity. A wallet address may identify an account on an exchange, and may be created and managed by an exchange. The user may request a transaction (e.g., a transfer transaction) such as a transfer (e.g., funds transfer) using the wallet address. According to some example embodiments, the user may input the transfer request into the electronic device 110 and the electronic device 110 may provide the transfer request to the first party exchange.
In operation S62, the transaction processing 410 may determine a target exchange to which the user desires to transfer an amount using the recipient wallet address. That is, the transaction processing 410 may recognize the transfer request to the second party exchange (e.g., the server 160) by verifying the target exchange corresponding to the recipient wallet address. According to some example embodiments, the recipient wallet address may include information (e.g., a value, format, etc.) that identifies the exchange to which the recipient wallet address corresponds, and the transaction processing 410 may identify the second party exchange using the recipient wallet address based on this information.
In operation S63, the transaction processing 410 may set a lock on a transfer request quantity in cryptocurrency assets held by the user on the first party exchange. As another example, the transaction processing 410 may set a lock on a quantity that is obtained by adding a predetermined (or, alternatively, desired) quantity or amount to the transfer request quantity, or a quantity that is obtained by adding a predetermined (or, alternatively, desired) ratio to the transfer request quantity (e.g., transfer request quantity+α), in the cryptocurrency assets held by the user on the first party exchange. The transaction processing 410 may first set a lock on the transfer request quantity in assets of the user immediately (or promptly) after confirming the target exchange or immediately (or promptly) after receiving the transfer request.
In operation S64, the transaction processing 410 may call a deposit API of the target exchange. That is, the transaction processing 410 may call the deposit API, for deposit from the first party exchange account on the target exchange, to the recipient wallet address.
In operation S65, the transaction processing 410 may deposit the quantity requested by the user, to be transferred to the recipient wallet address, according to calling of the deposit API. The transaction processing 410 may provide a rapid transfer by immediately (or promptly) applying, to the recipient wallet address, the quantity requested by the user to be transferred through an internal transaction using the first party exchange account on the target exchange (e.g., the server 160). According to some example embodiments, the first party exchange account is an account established by (or for) the first party exchange on the target exchange. According to some example embodiments, the first party exchange account includes funds (e.g., cryptocurrency) of the first party exchange for use in performing immediate transfers.
In operation S66, as the deposit from the first party exchange account to the recipient wallet address is processed, the transaction processing 410 may verify a deposit complete response (e.g., from the deposit API).
In operation S67, once the deposit to the recipient wallet address is completed, the transaction processing 410 may move at least a portion of the locked quantity from the user assets on the first party exchange to a first party exchange balance. The transaction processing 410 may apply the locked quantity in the user assets to a first party balance (e.g., after pre-deposit processing) from the first party exchange account to the recipient wallet address without using the blockchain network 330. Here, if a lock is set on a quantity that is obtained by adding a predetermined (or, alternatively, desired) quantity or amount to the transfer request quantity, or a quantity that is obtained by adding a predetermined (or, alternatively, desired) ratio to the transfer request quantity (e.g., transfer request quantity+α), the transaction processing 410 may apply a quantity less than the locked quantity and greater than or equal to the transfer request quantity in the user assets to the first party balance. According to some example embodiments, the transaction processing 410 may move a portion of the user assets equal or similar to the amount of the transfer transaction from a user account at the first exchange to an exchange account at the first exchange, thus compensating the first exchange for the deposit transaction performed at the target exchange. According to some example embodiments, this portion of the user assets corresponding to the transfer function may be transferred to the first party exchange account on the target exchange in a settlement process discussed further below in connection with FIG. 7.
In operation S68, when the deposit to the recipient wallet address and applying the same to the first party balance are all completed, the transaction processing 410 provides a notification indicating that a transfer (e.g., a withdrawal) is completed to the user that has requested the transfer.
Therefore, in response to the transfer request from the first party exchange to the second party exchange, the transaction processing 410 may support the transfer from the first party exchange account on the second party exchange to the recipient wallet address, that is, the immediate transfer through the internal transaction on the second party exchange, instead of the transaction using the blockchain network 330.
FIG. 7 is a flowchart illustrating an example of a settlement process according to an immediate transfer according to some example embodiments.
Referring to FIG. 7, in operation S71, the settlement processing 420 periodically verifies a balance of a first party exchange account opened on a second party exchange. For an immediate transaction, the balance of the first party exchange account on the second party exchange should be maintained at a predetermined (or, alternatively, desired) level or more at all times. Therefore, it is desirable to periodically check the balance.
In operation S72, the settlement processing 420 determines whether to make an additional deposit according to the balance of the first party exchange account through balance checking. When the balance of the first party exchange account is less than a set balance, the settlement processing 420 enters an additional deposit process. Here, the set balance may be determined based on statistical information of transactions related to the first party exchange account for a recent predetermined (or, alternatively, desired) period. Here, the statistical information may be an average transaction amount related to the first party exchange account for the recent predetermined (or, alternatively, desired) period or transaction trend for a predetermined (or, alternatively, desired) period. For example, the set balance may be determined based on trading volume using the first party exchange account for the recent predetermined (or, alternatively, desired) period. According to an increase in the recent trading volume, the set balance may be determined to be higher. As another example, an exchange-by-exchange deposit balance opened on the second party exchange may be collected and the average balance may be used as the set balance.
In operation S73, the settlement processing 420 may create a transaction for withdrawal of a quantity for the additional deposit. For example, the additional deposit quantity (also referred to herein as a deposit quantity) may be determined based on a difference amount between the current balance and the set balance. As another example, the additional deposit quantity may be determined based on a trading balance using the first party exchange account for the recent predetermined (or, alternatively, desired) period. According to an increase in the recent trading volume, the additional deposit quantity may be determined to be higher. According to some example embodiments, the additional deposit quantity may include an amount (e.g., cryptocurrency amount) corresponding to the transfer transaction discussed in association with FIG. 6.
In operation S74, the settlement processing 420 applies a fee rate to the transaction for the additional deposit and submits the transaction with the applied fee rate to the blockchain network 330. The term “transaction fee” refers to price paid to a miner that serves to perform a transaction in a blockchain and to create and store a transaction history block, and may be determined based on a transaction scale and a fee rate.
In operation S75, the settlement processing 420 waits for mining by a miner for the transaction submitted to the blockchain network 330. Mining for the transaction on the blockchain network 330 may be performed by the miner (e.g., the electronic device 120).
When the transaction submitted to the blockchain network 330 is mined by the miner, the additional deposit quantity according to the corresponding transaction may be deposited to the first party exchange account on the second party exchange in operation S76.
Therefore, when the additional deposit is to be made due to settlement according to the immediate transfer, the settlement processing 420 may perform a transfer from the first party balance on the first party exchange to the first party exchange account on the second party exchange using a transaction through the blockchain network 330.
As described above, according to some example embodiments, a processing time of a cryptocurrency trading may be significantly reduced by providing an immediate transfer through an internal transaction, using a first party exchange account opened on a second party exchange instead of a transaction using a blockchain network, in response to a transfer request to the second party exchange.
For example, conventional devices for cryptocurrency trading process transfer transactions (e.g., funds transfers) between exchanges through a blockchain network. However, processing such a transaction in a blockchain network involves discovery and mining of the transaction by a miner. Accordingly, the conventional devices for cryptocurrency trading experience excessive delay in processing transfer transactions between exchanges.
However, according to some example embodiments, improved devices for cryptocurrency trading are provided. For example, the improved devices process transfer transactions (e.g., funds transfers) between two exchanges as an internal transaction, using a first party exchange account opened on the second party exchange, without using the blockchain network. Subsequently, a settlement transaction is performed between the two exchanges that is processed through the blockchain network. However, processing the settlement transaction through the blockchain network does not delay the processing of the transfer transactions. Accordingly, the improved devices for cryptocurrency trading overcome the deficiencies of the conventional devices to at least reduce transfer transaction processing delay.
